sills 12. The vmembers 16 thus combined into a girder or frame have thereforetwo movements,v the longitudinal adjustment in the box-frame 18 and a racking or oscillating motion upon the trunnions 20. Said frame 16 carries upon its upper end a transv verse shaft 22 journaled in boxes 23, 24, the latter being secured to the u' per ends of the frame members 16 while the trames are borne upon the outer extremities of a cross piece of angle iron 25 securely bolted to the members lladjacent to their ends. Upon the shaft 22 external to, but in close Aproximity with, the side beams 16 are iixedpentagonal sprocket wheels 26. There are two pairs of these' Wheels, those just described and a duplicate pair carried on the opposite end of the adjustable' frame 16 the shaft of the latter pair being supported upon arms 27, 'which carry the journal boxes 28 which are rooved and adapted to slide in slots 29 lorined 'in said arms 27 and are adjustable longitudinally of the 'frame b means of screws 30. The sprocket whee s 26 engage connecting sprocket chains 31 to which the excavating elements 32 are attached. Seven such devices are 'shown in Fig.- 1, secured to the elevating chain 31, but it is evident that the number can be varied to suit conditions as they occur. 'lnese devices are each composed of a bed-plate 33, rigidly fixed to the parallel chains Slin any suitable manner. To the said chains are attached 'arms 34, pivoted to thc link at 34, their other ends )eine offset so that they can extend over saidzlaed plate to engage sockets 35 formed integral with a back plate 36, from `si'hich project digqing points 37, preferably fashioned like the shovel points of a cultivator, although this feature may he varied if desirable, To the rear face ot cach back plate attached duplicate friction rollers 38. Upon the outer ends of the shaft 22 are sprockets 530 for driving said shaft, motion being inlparted thereto through sprocket chains 4U, which engage sprockets 41 fixed esseci to a counter shaft 42 carrying an intermediate gear wheel 43 meshin with a smaller wheel 411 carried by a main s aft 115 uponthe end of which is mounted a driving pulley 46 which receives lmotion from a ower 461 represented diagrammatically in 1 and 6.

To .prevent any rocking movement of the) and 4S are removed and others .of different lengths substituted therefor, o1" a series of holes may be formed4 in the frame'to ,facilitate the adjustment of the same tie pieces. From thc box frame 18 are projecting arms carrying rollers ,49 which engage the chains' 31 to prevent their sagging sufficiently to in terfere with the mechanism attached to' the said frame. Upon the opposite or under, side of the'ira'me are secured channel irons 50 with which the rollers 38. oi' the excavating elements engage duringr their travel upwardly along the face of thejframe, the object being` as in the case of the o posite rollers 49 to prevent interference with Since the frame 16, as previously stated, is free to move longitudinally in the box 'frame 18 some provision must be made ito readily shift it to various positions and to securely holdit in place when so adjusted. For this purpose a cable 51 is provided which passes through compound pulley blocks 52, 53, the

former being'attached to the frame 18, which serves as the fixed point, the latter being secured to the girder 16 which is the-Weight to be moved. A sufficient number of pulleys areA employed to provide enough power to easily move the girder and its attachments in either direction, up or down. The free ends oi the cables after leaving,r the pulleys are carried up to windlasses 54:.` A Worm .55 meshing with a wheel 56 attached to the windlass shaft'54 is actuated by bevel gears 57 which are' operated by a hand wheel 58 at the side ol' the machine. An endless apron 59 is arranged transversely to the main sills the apparatus. i

12 and is carriedover suitable rollers 6() the shafts of which are journaled in boxes 61 mounted. upon beams 13a. Upon the shaft of one of the said rollers 60 is mounted a sprocket 62 connected by a chain 63 with a sprocket 64 actuated by a pair of gears 65, one of whichv is carried on the same shaft as the sprocket 64 and the other upon a parallel shaft 66. 4vll/'hen it is desired to reverse the movement of the apron 59, which is necessarv when theendless apron is extended laterally upon the opposite side of the frame 12 which is done by shifting the supporting from the said bed plate ,and the accumulated material Will fall by avity throu h the gap thus formed, and Wi be de osited upon the endless apron 59 which lies irectly beneath. As the elements pass down the opposite side the arts ,Will resume their initial position relative to each other. On passing around the lower sprocket the same movement will take place, the initial position, lioweverbeing quickly resumed just at the beginning of the upwardf`ourney It will be understood that the fee in movement through the Inedium of the ,ca le 87, the conveying movement: roduced by means of the endless apron 59 an the combined excavating and elevating motion of the sprocket chain 81 and attachments can be readily adjusted relatively to each other so that the operation will/be mutual. and simultaneous.
